Error: No CLR runtime found (dump collected with 8.0.0)
ivonin opened this issue · 5 comments
Description
Full dump collected with dotnet-monitor
can't be properly analyzed with dotnet-dump
:
dumpheap -stats
results in an error: "No CLR runtime found. This means that a .NET runtime module or the DAC for the runtime cannot be found or downloaded."runtimes
doesn't indeed show any runtimes.
Configuration
- The process that the dump is collected from is running inside a container based on
mcr.microsoft.com/dotnet/aspnet:8.0-jammy
. - We run
dotnet-dump
on Ubuntu 22.04 (jammy). dotnet-dump --version
:8.0.510501+8c08c89a0643d31db91e119b1adb463be3e0ffe5
.- dotnet-monitor
/info
output:8.0.0-rtm.23559.8+8c7f7afdfa9b2472bb1d791e953480f214586ae6
; runtimeVersion=8.0.0
.
Regression?
We didn't have such problems with .NET 7.
Other information
We can't unfortunately provide the dump in question as it contains sensitive data. The issue is, however, persistent, and we're able to reproduce it 100% of the time (every single dump taken from that environment is un-analyzable on any developer machine).
Hello! Is it possible to get any updates on this? Is it likely to be a bug that will get fixed?
Does the Ubuntu 22.04 you are running dotnet-dump analyze
have a .NET 8 or less SDK installed? Or are using the single-file dotnet-dump and/or running in the container with the image?
The Ubuntu machine we use to analyze the dump does indeed has net8 sdk installed. The same machine can be used to analyze net8 dumps collected from a debian container without issues.
